    Study Notes

    Displacement in SHM

    • Displacement in SHM refers to the distance of an oscillating object from its equilibrium point.
    • It varies sinusoidally with time.

    Amplitude in SHM

    • Amplitude is the maximum displacement of an object from its equilibrium position during oscillatory motion.
    • It is a measure of the oscillation's intensity.

    Relationship Between Angular Frequency and Natural Frequency

    • Natural frequency (f) represents the frequency at which an object oscillates without any external forces.
    • Angular frequency (ω) is related to natural frequency by the equation: ω = 2πf.
    • Essentially, they describe the same thing, but angular frequency is expressed in radians per second.

    Critical Damping

    • Critical damping is the damping level that rapidly returns an oscillating system to its equilibrium position without oscillation.
    • This is the optimal damping for systems where oscillations are undesirable.

    Resonance

    • Resonance occurs in a system when the driving frequency matches the natural frequency of the system.
    • This leads to a large amplitude of oscillations, potentially causing damage or instability.

    Damped Oscillations

    • Damped oscillations occur when energy is gradually lost from an oscillating system, reducing the amplitude of oscillation.
    • This loss of energy can be due to various factors like friction.

    Forced Oscillation

    • Forced oscillation involves applying a periodic external force to an oscillating system.
    • The system is forced to oscillate at the driving frequency of the external force.

    Damping

    • Damping is the process of energy dissipation from an oscillating system, causing its amplitude to decay over time.
    • The damping effect can be caused by friction, air resistance, or other dissipative forces.
